Abstract

L'invention concerne un procédé de commande de routage de paquets vers un noeud mobile dans un réseau de commutation de paquets qui comprend une infrastructure de noeuds de commutation de paquets, lesdits noeuds comportant plusieurs noeuds de noyaux fixes et plusieurs noeuds d'accès vers les voies de routage définies par le renvoi du prochain saut. Ce procédé peut s'appliquer dans ladite infrastructure pour une adresse de réseau donnée, ledit renvoi étant défini en réponse à des processus de définition de routage, spécificiant une caractéristique d'une route passant à travers un noeud d'accès. Ledit procédé consiste à modifier ledit renvoi de prochain saut, dans au moins un noeud de commutation de paquets en réponse à la mobilité de l'hôte mobile à partir d'un premier noeud d'accès vers un second noeud d'accès, par un processus de définition de routage, de telle manière qu'une fois terminé ledit processus: les premières données de protocole de routage sont contenues dans un premier ensemble de noeuds de commutation de paquets, lesdites premières données spécifiant une caractéristique d'une première route passant à travers ledit premier noeud d'accès, et les secondes données de protocole de routage sont contenues dans un second ensemble de noeuds de commutation de paquets, lesdites secondes données spécifiant une caractéristique d'une seconde route passant à travers ledit second noeud d'accès.
